ERNEST HILL, OF SHEFFIELD, ENGLAND.

PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 479,002, dated July 19,1892.

Application filed September 12,1891. Serial No. 405,559. (ModeL)Patented in England June '7, 1890, No. 8,796.

To all whont it may concern.-

Be it known that I, ERNEST HILL, a British subject, residing atNether-Edge, Sheffield,in the county of York, England, have invented anew and useful Improvement in the Construction of Pavements, (for whichI have obtained a patent in Great Britain, No. 8,796, bearing date June7, 1890,) of which the following is a specification.

The object of my present invention is to prolong the life of the roadwayby constructing a stud that can be produced in wrought material to givea better grip for the animals feet and to reduce the cost ofmanufacture.

My invention is illustrated in the annexed sheet of drawings, in which-Figure 1 is a perspective elevation of one of theimproved studs made ofwrought-steel; Fig. 2, a plan of stud; 3, a plan of roadway with squareblocks; Fig. 4, a plan of roadway with oblong blocks.

In carrying my invention into effect I make the studs from bars orplates of Wrought-steel, steel-iron, or other Wrought material ofsuitable strength and durable quality, consisting of an uprightrectangular part A, resembling a piece of angle-iron and having a baseor foot 13, made from the same continuous material, bent back at a rightangle to the upright A.

In order to obtain a support for the blocks of wood 0 or other materialused to form the roadway, where they fit into the hollow or inside ofthe angular upright A, and to sustain the said blocks ar -the requiredlevel, also to give a further support to the upright, I partly cut orpunch a flap of metal D .ont of the base B or out of the uprightA andturn it into the position shown in the drawings, Figs. 1 and 2, and bythe application of force I bring it to a level with the part B andinside the angle of upright and leaving the whole foot level. The studsso constructed are then ready to be used as shown in Figs. 3 and 4; butother arrangements of the studs may be made, as may be preferred.

The base-plates or feet of the studs are embedded in a thin layer ofasphalt upon aconcrete foundation and the blocks of wood or othermaterial areplaced in position,as shown, so that they rest upon the saidlayer of asphalt and upon a portion of the base or foot of each stud andin order to afford a better grip for the animals feet. I prefer to allowthe studs to project slightly above the face of the blocks-say, forexample, one-eighth of an inch.

In Fig. 3 it will be seen that I use square blocks, while in Fig. 4 Iuse oblong blocks, arranged to break-joint in the manner of brickwork.The interstices or spaces between the blocks, due to the interveningstuds, I fill up with pitch or suitable cement.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

A pavement consisting of a suitable foundation upon which is superposeda series of rectangular blocks connected at their angles bywrought-metal studs having a horizontal base B, an integral tongue D,cut therefrom and bent in opposite direction in the same plane andhaving the other end of the plate struck up into vertical angular form,substantially as and for the purpose set forth.

ERNEST HILL.
